The Impact of Voting by Mail on Voter Behavior

Most of the studies of voter behavior have dealt with voter turnout, but few have looked at other aspects of voting behavior that could be linked to balloting method. A reasonable amount of information has now accumulated about the impact of the shift from polling place elections to voting by mail on turnout, rolloff, drop-off, differences in voting for partisan offices and referenda, and differences in straight-ticket voting. This article analyzes recent time series of voting data in Oregon to assess the impact of the shift in voting method on these issues. The analysis includes data at the state, county, precinct, and individual levels, including individual ballots. The results suggest new criteria for evaluating shifts from one voting method to another that may be applied to other electoral reforms, such as those that will result from the Help America Vote Act.
